Problems solved by technology

In addition, the skin comprises harmful bacteria such as Propionibacterium acnes and Staphylococcus aureus, which are responsible for a number of skin disorders.
Antibacterial cosmetic compositions existing in prior art affect both the beneficial bacteria and harmful bacteria present on the skin, and the excessive use of said compositions weakens the natural defenses of the skin, leaving it more vulnerable to pathogens.
Said antibacterial cosmetic compositions may have toxicity to the user and the environment and do not prevent the recolonization.

n In Vitro of the Antiaging Effect

[0027]Bifidobacteria were tested both active and inactivated in conditioned medium templates to assess whether they were able to indirectly stimulate fibroblasts. The model consists of conditioned medium in the incubation of keratinocytes with the probiotics, the removal of the supernatant and this one further incubated with fibroblasts. The cytokines profiles were measured in the supernatants of both cells and matrix proteins were measured in the supernatant of the fibroblasts.

[0028]The following tables show the results of the tests, indicating whether there was an increase or decrease in the profiles of the cytokines.

rial Selectivity

[0032]The antimicrobial activity was tested in vitro with a variation of the inhibition halo model, where the live bifidobacteria were plated and then inactivated before the inoculation with microorganisms present in the microbiota of the human skin: Propionibacterium acnes (ATCC 6916 and ATCC 51277); Staphylococcus aureus (ATCC 29213 and ATCC 25923); and Staphylococcus epidermidis (ATCC 12228).

nism Removal and Recolonization Inhibition

[0034]An evaluation in vivo of the effect of a solid cosmetic composition according to the present invention (soap), compared to a solid composition commercially available (soap) was performed. In this experiment, the manipulation of cell phone, computer, money or any interventions in the hands, or use of any other washing products, etc., was not allowed.

[0035]Half of the volunteers washed their hands with the soap according to the present invention and the other half with the soap commercially available (composition that comprises triclosan, triclocarban, DMDM hydantoin, net).

[0036]The effectiveness of microorganism removal was higher with the soap according to the present invention than when using the commercially available soap. The soap of the invention cleaned the hands as effectively as antibacterial soap in the art, removing 70% of bacteria and 50% of the fungi. Measurements 30 minutes after the washing showed that the commercially av...

Abstract

The present invention relates to a probiotic cosmetic formulation for the cosmetic treatment of the skin, comprising a microbiota and a cosmetically acceptable carrier. Preferably, betaines and/or prebiotic agents may be incorporated into said formulation. The invention also relates to the use of a microbiota in preparing said probiotic cosmetic formulation of the invention, and a method for the cosmetic treatment of the skin, which comprises administering to the skin of an individual the probiotic cosmetic formulation of the invention.

Description

FIELD OF INVENTION[0001]The present invention relates to cosmetic compositions that may be present in soap bars, emulsions, gels, creams or lotions comprising probiotic ingredients and cosmetically acceptable excipients.PRIOR ART[0002]The human skin defines the boundary between the external and the internal body environment, functioning as the first line of defense against external pathogens. But it also contains several symbiont microorganisms such as bacteria, fungi and viruses, and the organization of such microorganisms is called microbiota.[0003]Particularly on the skin, there are bacteria important for maintaining the firmness, resistance and natural mechanisms of skin defense, fundamentally contributing to good skin health maintenance. Staphylococcus epidermidis is the main bacteria of the skin, for it synthesizes protease, keratinase, lipases and nucleases that contribute to the physiological renewal mechanisms of the skin even during aging.[0004]In addition, the skin compri...
